TECHNICAL FIELD
[0001] The present application relates to the technical field of reaction kettles, and more particularly to a heating reaction kettle. BACKGROUND
[0002] A reaction kettle for liquid sodium and ammonia is generally used to synthesize some chemicals, such as sodium nitride, sodium amide, etc. The working principle of this kind of reaction kettle involves the reaction of liquid sodium and ammonia gas under high temperature conditions. Liquid sodium is put into a sodium ammonia kettle, the feed inlet of the sodium ammonia kettle is closed, and ammonia gas is quantitatively and constantly fed through a flowmeter after being heated to 360-400℃ by electricity. Liquid sodium reacts with ammonia gas to generate sodium amide, which is used for the next reaction. Liquid sodium amide can also be dried by a roller, cooled and sliced, and then sold as a sodium amide product. Hydrogen generated by the reaction is sent to an alkali pot for combustion through a water seal tank. The chemical equation for the reaction of liquid sodium and ammonia gas is as follows:
[0003] 2Na + 2NH3→ 2NaNH2 + H2.

[0028] In the embodiment of the present application, liquid sodium is poured into the inside of the reaction kettle body 1 through the liquid inlet pipe 101, and the reaction kettle body 1 is rapidly heated to 360-400°C by the electromagnetic heating mechanism 104. The electromagnetic heating mechanism 104 can refer to the relevant description in the prior art, which will not be described here. The electromagnetic heating mechanism 104 has the effects of energy saving, environmental protection, and rapid heating. The reaction kettle body 1 can be made of metal.
[0029] After being heated to 360-400°C, ammonia gas is added to the inside of the reaction kettle body 1 through the gas inlet hose 102. The ammonia gas passes through the fixed pipe 701 and is sprayed out from the air injection hole 703 of the stirring pipe 702. In the process of adding ammonia gas, the driving assembly 3 drives the transmission assembly 4 to rotate, the transmission assembly 4 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the mounting assembly 6 to rotate reciprocally. Then, the ammonia gas is sprayed into the liquid sodium through the air injection hole 703 of the stirring pipe 702, and the stirring pipe 702 can stir the liquid sodium at the same time, so that the ammonia gas sprayed out of the air injection hole 703 can fully contact with the liquid sodium, thereby improving the reaction efficiency.
[0030] The mounting assembly 6 includes a top plate 601 fixedly connected to the bottom of the rotating rod 5, a side plate 602 fixedly connected to the bottom of the top plate 601, a bottom plate 603 fixedly connected to the bottom of the side plate 602, a plug rod 604 fixedly connected to the top of the bottom plate 603, and a mounting plate 704 fixedly sleeved with the top of the fixed pipe 701.

[0031] The plug rod 604 and the fixed hole 705 are mutually matched. The mounting plate 704 is connected with the bottom plate 603 by inserting the plug rod 604 into the inside of the fixed hole 705, so as to fix the mounting plate 704 in the horizontal direction. When the mounting assembly 6 rotates under the driving of the rotating rod 5, the mounting plate 704 can rotate, thereby driving the fixed pipe 701 to rotate.

Since the rack plate 404 is engaged with the transmission gear 501, the rack plate 404 drives the transmission gear 501 to reciprocate during horizontal reciprocation, so that the rotating rod 5 and the stirring pipe 702 also reciprocate, and the ammonia gas is rotated clockwise or counterclockwise to further improve the sufficiency of contact between the ammonia gas and the liquid sodium.
[0036] The driving assembly 3 comprises a fixed plate 301 fixedly connected to the top of the support plate 2, a cylindrical rod 302 movably sleeved on the fixed plate 301, a rotating disc 303 fixedly connected to the back of the cylindrical rod 302, a first cylindrical block 304 fixedly connected to one side of the back of the rotating disc 303, and a connecting plate 305 movably sleeved on one end of the first cylindrical block 304, wherein the other end of the connecting plate 305 is connected with the rack plate 404.
[0037] When the rotating disc 303 rotates with the cylindrical rod 302, the first cylindrical block 304 also rotates around the cylindrical rod 302 with the rotating disc 303. Since one end of the connecting plate 305 is movably sleeved on the first cylindrical block 304 and the other end is connected with the rack plate 404, the connecting plate 305 drives the rack plate 405 to reciprocate horizontally left and right when the first cylindrical block 304 rotates around the cylindrical rod 302 under the restriction that the rack plate 404 can only move horizontally.
[0038] The rack plate 404 is fixedly connected with two connecting blocks 405 on the right side, the two connecting blocks 405 are fixedly connected with a second cylindrical block 406, and the second cylindrical block 406 is movably sleeved on the end of the connecting plate 305 away from the first cylindrical block 304.

[0040] The driving assembly 3 further comprises a driving motor 307 fixedly connected to the right side of the reaction kettle body 1, the output shaft of the driving motor 307 is fixedly connected with a worm 308 penetrating through the reaction kettle body 1, the front surface of the cylindrical rod 302 is fixedly sleeved with a worm wheel 306, and the worm 308 is engaged with the worm wheel 306.
[0041] The driving motor 307 is started, the driving motor 307 drives the worm 308 to rotate, the worm 308 drives the worm wheel 306 to rotate, and since the worm wheel 306 and the rotating disc 303 are both fixedly sleeved on the cylindrical rod 302, the rotating disc 303 can be driven to rotate, so that the rack plate 404 can be driven to move.
[0042] The top of the reaction kettle body 1 is provided with a pressure detector 103, the top of the reaction kettle body 1 is provided with a gas outlet pipe 105, and the bottom of the reaction kettle body 1 is provided with a liquid outlet pipe 106. The hydrogen obtained after the reaction can be discharged from the top through the gas outlet pipe 105, and the sodium amide can be discharged from the bottom through the liquid outlet pipe 106. The pressure detector 103 can monitor the pressure in the reaction kettle body 1 during the reaction. It should be noted that the top of the reaction kettle body 1 is not sealed by the supporting plate 2, so that the hydrogen generated by the reaction can be discharged from the top.
[0043] The working principle and use process of the present application are as follows:
[0044] The liquid sodium is poured into the inside of the reaction kettle body 1 through the liquid inlet pipe 101, and after being heated to 360-400 DEG C by the electromagnetic heating mechanism 104, the ammonia gas is introduced through the gas inlet hose 102, the fixed pipe 701 and the stirring pipe 702. In the process of introducing the ammonia gas, the driving motor 307 is started to drive the worm 308 to rotate, the cylindrical rod 302 is driven to rotate through the meshing action of the worm wheel 306, so that one end of the connecting plate 305 can be circularly oscillated by the rotating disc 303, and then the connecting plate 305 can drive the rack plate 404 to move back and forth in the left and right directions, the rack plate 404 and the transmission gear 501 are engaged, the rotating rod 5 drives the mounting assembly 6 to rotate back and forth, and then the ammonia gas is sprayed into the liquid sodium through the gas injection hole 703, the stirring pipe 702 can stir the liquid sodium at the same time, so that the ammonia gas sprayed out of the gas injection hole 703 can fully contact with the liquid sodium, and the reaction efficiency is improved.
